Q

What is the definition of a basic service?

A

A basic service is a type of UK FIS provided for the purpose of giving advice and information useful for the safe and efficient conduct of flights.

This may include;

  • weather information
  • changes to servicability of facilities
  • conditions at aerodromes
  • general airspace activity information
  • any other information likely to affect safety

The avoidance of other traffic is solely the pilot’s responsibility.

Q

What is the definition of a procedural service?

A

An air traffic service where, in addition to the provisions of a Basic Service, the controller provides restrictions, instructions and approach clearances, which if complied with, will achieve deconfliction minima against other aircraft participating in the procedural service. Neither traffic information nor deconfliction advice can be passed with respect to unknown traffic.

Q

Can you provide a Procedural Service below the terrain safe level?

A

Yes as a procedural service is available at all levels.

However if a pilot wishes to operate below ATC unit terrain safe levels, unless on departure from an aerodrome when climbing to the ATC unit’s terrain safe level, or when following notified instrument approach procedures, controllers shall advise the pilot of the terrain safe level and remind him of his terrain responsibilities.

Q

What is essential traffic information and what elements shall it include?

A

Essential traffic is traffic which is separated for any period by less than the specified standard separation. It is normally passed in situations when ATS surveillance systems are not available.

Essential traffic information passed to an aircraft shall include;

  1. Direction of flight of conflicting aircraft
  2. Type of conflicting aircraft
  3. Cruising level of conflicting aircraft and ETA for the reporting point, or for aircraft passing through the level of another with less than the normal separation, the ETA for the reporting point nearest to where the aircraft will cross levels; and,
  4. Any alternative clearance.

Q

What are the reduced separations in the vicinity of the aerodrome and which can you utilise as the APP ATCO?

A

As the APP ATCO, in the vicinity of aerodromes, the standard separation minima may be reduced if:

(1) each aircraft is continuously visible to the pilots of other aircraft concerned and the pilots report that they can maintain their own separation; or
(2) when one aircraft is following another, the pilot of the succeeding aircraft reports that he has the other aircraft in sight and can maintain own separation.

As an APP ATCO you can also ask the Aerodrome ATCO to assist with reduced separation in the vicinity of the aerodrome and release the aircraft RSYD subject to “adequate separation can be provided by the aerodrome controller when each aircraft is continuously visible to this controller.”

Q

When can pilots be cleared for a visual approach?

A

To expedite traffic at any time, IFR flights, either within or outside controlled airspace, may be authorised to execute visual approaches if the pilot reports that he can maintain visual reference to the surface and:

(1) the reported cloud ceiling is at or above the level of the beginning of the initial approach segment; or
(2) the pilot reports at any time after commencing the approach procedure that the visibility will permit a visual approach and landing, and a reasonable assurance exists that this can be accomplished.

Controllers should not clear an aircraft for a visual approach when the RVR is less than 800 m. If a pilot requests a visual approach when the RVR is less than 800 m, controllers should inform the pilot that this type of approach is unavailable and request the pilot’s intentions.

* Separation minima based on time cannot be achieved unless the whole sixty seconds of each minute specified is permitted to elapse.

28
Q

Define the transition level

A

Transition level is the lowest Flight Level available for use above the transition altitude. It is determined from the table in Appendix A as follows:

(1) Within controlled airspace by the controlling authority and it will normally be based on the QNH of the major aerodrome;
(2) Outside controlled airspace by the Aerodrome Operator and based on the aerodrome QNH.

29
Q

Define Transition Altitude

A

Transition altitude is the altitude at or below which the vertical position of an aircraft is controlled by reference to altitude (or height when QFE is used). Wherever possible there is a common transition altitude for aerodromes within a control zone. Unless otherwise notified the transition altitude for civil aerodromes is 3000 feet.

30
Q

Define transition layer

A

Transition layer is the airspace between the transition altitude and the transition level. Within the UK, the first available flight level above the transition altitude is separated from the transition altitude by a minimum pressure interval corresponding to a nominal 1000 ft.

31
Q

34
Q

What are the visual flight rules below FL100, and above 3000ft AMSL or below FL100 and above 1000ft above terrain whichever is higher, in Class G airspace?

A

Horizontal distance from cloud 1500 M and 1000ft vertically with a flight visibility of 5KM.

35
Q

What procedures shall be followed in the event of a failure or navigation lights of an aircraft?

A

The ANO requires that an aircraft shall not depart from an aerodrome at night if there is a failure of any light which the ANO requires to be displayed and the light cannot be immediately repaired or replaced. If the aircraft is in flight the aircraft shall land as soon as it can safely do so, unless authorised by ATC to continue its flight. Controllers should take the following into consideration before authorising the flight:

(1) Normally permission should only be granted if flight is to be continued wholly within UK controlled airspace classes A-D. Flight outside the UK under these conditions may not be authorised unless permission to continue has been obtained from the adjacent controlling authority;
(2) If the pilot’s intention is to fly outside controlled airspace or within Class E airspace, he should be instructed to land at the nearest suitable aerodrome. Selection of this aerodrome is the responsibility of the pilot although he may request information to assist him in making his decision. Under certain circumstances the pilot may decide that the nearest suitable aerodrome is his original destination.

36
Q

Describe in detail the different types of track separation utilising a VOR and associated DME/TACAN station.

A

Track separation shall be established by requiring aircraft to fly on specified tracks, which are separated by a minimum amount appropriate to the navigation aid employed. Aircraft must be within the designated operational coverage of a VOR or the protected range of an NDB as shown in the UK AIP (AD) section.

Using a VOR and associated DME/TACAN station. Both aircraft must have reported established on radials at least 20° apart;

Aircraft diverge and one aircraft is 15 miles from the DME/TACAN station.

Aircraft converge and one aircraft is 30 miles from the DME/TACAN station.

One aircraft inbound and the other outbound from the VOR station provided that the outbound aircraft is at least 20 miles OR the inbound at least 30 miles from the station.

Using VOR radials. When one aircraft is a time equivalent of 15 miles or 4 minutes (whichever is the greater) from the VOR and both aircraft have reported established on radials which diverge by 20° or more;

Aircraft diverging: Using VOR radials. Both aircraft must have passed a VOR on tracks diverging by 45° or more and have reported established on the relevant radials.

37
Q

Describe in detail track separation using specified tracks from an NDB

A

Using specified tracks from an NDB. When one aircraft is the time equivalent of 15 miles or 4 minutes (whichever is the greater) from an NDB and both aircraft have reported established on tracks which diverge by 30° or more.

If a pilot reports that he suspects the accuracy of the NDB indications this separation shall not be used.

38
Q

What is the definition of same, crossing and reciprocal track?

A

Same track, when the track of one aircraft is separated from the track of the other by less than 45°.

Reciprocal track’, when the track of one aircraft is separated from the reciprocal of the other by less than 45°;

‘Crossing track’, intersecting tracks which are not classed as ‘same’ or ‘reciprocal.

39
Q

From what point does intermediate wake turbulence apply?

A

That part of the instrument approach procedure when the aircraft reports beacon outbound on the procedure to the report of base turn complete or localiser established.

40
Q

Describe a TCAS Traffic Advisory warning and how long before the assumed collision will the warning become present.

A

Traffic Advisory (TA) warning. Pilots are advised not to take avoiding action on the basis of TA information alone but may ask for traffic information. Pilot looks for conflicting aircraft visually. Does NOT manoeuvre. Typically 45 seconds before the assumed collision.

41
Q

Describe a TCAS Resolution Advisory warning and how long before the assumed collision will the warning become present?

A

Resolution Advisory (RA) warning. Pilot receives advice to climb, descend or maintain their existing flight profile. Rate of climb or descent may also be given. Pilots are expected to respond immediately but have been instructed to restrict manoeuvres to the minimum necessary to resolve the confliction, advise the ATC unit as soon as is practical thereafter and return to their original flight path as soon as it is safe to do so. Typically 30 seconds before the assumed collision.
